The association of vascular diseases, such as atherosclerosis, with blood
flow properties such as wall shear stress has driven the use of computational
methods to model flow in the larger arteries of the human vascular system.
The problem presents a range of challenges from the non-Newtonian, pulsatile
nature of blood flow, operating at intermediate Reynolds numbers, to the
intricate geometric characteristics and distensible properties of the arteries.
In this presentation we will discuss the application of spectral/hp element
methods to the problem of vascular flow modelling. Starting with a reduced
model to simulation the full vascular system we will then consider the complex
flow modelling at arterial junctions and outline recent collaborative in-vivo
work in arterial bypass grafting.
